Answer:

The correct answer will be- Bacteria were able to utilize the food material in nine containers by producing respective enzymes.

Explanation:

The process of utilization of food material as a source of food depends on the Operon machinery of the Bacteria. The Operons gets activated in the presence of the inducer molecule which leads to the gene expression and the production of the enzymes to digest the food substance.

In the given condition, since the bacterial growth was observed in the nine containers out of ten shows that bacteria expressed the genes and produces enzymes to digest the substance in nine plates only and showed growth.

Thus, Bacteria were able to utilize the food material in nine containers by producing respective enzymes is the correct answer.

Explain what would happen to a person if they eat/drink something that their body does not have an Enzyme for?
mestny [16]

Answer:

People with lactose intolerance may have a variety of symptoms. It all depends on how much dairy or how many milk-containing foods the person eats and how little lactase the body produces.

Usually within 30 minutes to 2 hours after eating, someone with lactose intolerance will experience nausea, stomach cramps, bloating, gas, and diarrhea. This can be unpleasant, not to mention embarrassing if you're at school or out with friends.

Because many people may think they're lactose intolerant when they really aren't, it helps to see a doctor who can diagnose the condition correctly and advise you on ways to manage it.
